*)
The data of a module is updated with the minimum number of accesses.
(Example: There are 2 double word accesses for 8 bytes, for 16 bytes there are
4 double word accesses.)
**)
For I/Os which are plugged into the central rack or into the expansion rack, the specified
valule contains the runtime to the I/O module.
